Real-time Database
A real-time database is a type of database system that enables immediate data synchronization and updates across all connected clients in real-time, typically using a publish-subscribe model. It allows applications to receive live data changes without manual refreshes, making it ideal for collaborative and interactive features. These databases often use WebSockets or similar technologies to maintain persistent connections for low-latency data streaming.
Developers should use real-time databases when building applications that require live data updates, such as chat apps, collaborative tools (e.g., Google Docs), live dashboards, multiplayer games, or IoT monitoring systems. They are essential for scenarios where data consistency and immediate user feedback are critical, as they eliminate the need for polling and reduce server load by pushing updates only when changes occur.
